all whom it in ay concern:

Be it known that l, RALPH L. MORGAN, a citizen of the United States, residing at Worcester, in the county of "Worcester and Conunonwealthof Massachusetts, have invented a new and useful Improvement in ire-Drawing Machines, of which the following is a specification accompanied. by drawings, forming a part of the same, in which- Figure l is a plan view of a wire drawing; machine embodying my invention. Fig. 2 is a central sectional View of a wire drawing ca 'istaneinbodying my present invention. Fig. 3 a detached. view of a portion of a wire drawing capstan embodying my pesent invention, and illustrating the operation of the same.

Similar reference figures refer to similar parts in the different views.

My invention relates to an improvement in capstans for continuous wire drawing machines, and it has for its object to prevent the crowdingof the wire against the east'nr oli flange, and this object is accomplished by the i'sonstruction and arrangement of parts as hereinafter described and pointed out in the annexed claim. I

Referring to the accompanying drawings 1 denotes the fraineworl-r of a continuous wire drawing machine in which is journaled a driving shaft 2, provided with a pulley 3,-

having: a belt connection with a com uient source oi power. The shaft 2 is provided with pinion 4- which imparts motion to the shafts 5 and (3 through the gears 7 and 8. The wire 9, to be drawn, is usually taken from a coil or reel and is successively drawn through. the die boxes 10, 11, 12 and 13 supported in the usual manner in a die box i l. A. longitudinal movement in'il'iurtcd to the wire by which it is drawn through the rcd uciug dies by moans of a capstan .15 carried on the shaft AS the wire leaves the capstan 15 it passes beneath the die box Li and carried around the scored idler pulleys l0, l7 and 18 respectively. which serve to change the direction of the wire and return it to the next succeeding die. As the wire is delivered:

from the last die held in the box. 13, it wound into a coil upon the revolving drum ii, which draws the wire through the final die and winds it in a coil in the usual man no]. in machines of this class. Motion is ini parted to the drum 19 by a geared connection, not shown, with the shaft 6.

The capstan 15 which embodies my present invention is constructed as shown in sec tional view in Fig. 2, and consists of a series of disks Q0, 21, :22 and 93, which are held between a collar 24: on the shaft 5, and a nut 25 held upon the screw threaded end 26 of the shaft Clalnped between the disks are metallic wire seats 27, 28 and 29; The disks 20, 21 and 22 project beyond the peripheries of the wire seats and are provided with bevcledsiiirfaces 30, 31 and 32, as is common in wire drawingcapstans, said beveled projecting surfaces forming casting oil flanges which crowd the wire as it coiled. one or more times around the wire seats toward the seats.

My present improvement consists in forming the wire seats with beveled surfaces, as shown at 36, 37 and 38, Fig. 2. The position of the wire when coiled upon theseaf is illus trated in 3, in which the complete coil of wire 3% has been moved away from the beveled surface or casting oil llangc of the disk 20 by the tensile strain imparted to the wire, so thi'it there is a clear space between the coils of wire upon the wire seat 27, as shown at 39, Fig. 3.

The seats 27, .28 and are preferably torined of a metal harder than the wire to be drawn, to insure the slipping ot the wire over the beveled peripheries of the seats.

I claiin,

In a wire drawing capstan, a spindle having a collar, a plurality of spaced disks of dill'erent diameters, arranged on said spindle in order of sir. a plurality of spaced wire seats of dill'cront diau'icters, interposed in alternating relation to said disks, and arranged in order o'l size, each of said disks liking beveled on each suri'acc from the edge oi the adjacent wire seat to its periphery, to 't'oru'i casting oil flanges, and each o'l said wire seats having: its peripheral surface at an oblique angle to th 2 axis of said spindle, and

formin an obtuse angle with the ad'acen't 2" beveled surface of one of the adjacent disks, and. means carried on said spindle for holdinc" said disks and said wire seats against said (Ypllar.
